FIG. 1 is a block diagram illustrating a structure of a speakeraccording to some embodiments of the present disclosure.

A speaker 100 may include at least an earphone core 102, an auxiliaryfunction module 104, and a flexible circuit board 106.

In some embodiments, the earphone core 102 may receive electrical audiosignal(s) and convert the audio signal(s) into the sound signal(s). Theflexible circuit board 106 may facilitate electrical connection(s)between different modules/components. For example, the flexible circuitboard 106 may facilitate an electrical connection between the earphonecore 102 and an external control circuit and an electrical connectionbetween the earphone core 102 and the auxiliary function module 104.

In some embodiments, the earphone core 102 may include at least amagnetic circuit component, a vibration component, and a bracket thataccommodates the magnetic circuit component and the vibration component.The magnetic circuit component may be used to provide a magnetic field.The vibration component may be used to convert an electrical signalinput to the vibration component into a mechanical vibration signal soas to generate a sound. In some embodiments, the vibration component mayinclude at least a coil and an inner lead. In some embodiments, theearphone core 102 may also include an external wire. The external wiremay be capable of transmitting an audio current to the coil in thevibration component. One end of the external wire may be connected tothe inner lead of the earphone core, and the other end may be connectedto the flexible circuit board of the speaker. In some embodiments, thebracket may have a wiring groove. The external wire and/or the innerlead may be partially disposed of the wiring groove described in detailin other parts of the present disclosure.

In some embodiments, the auxiliary function module 104 may be used toreceive auxiliary signal(s) and perform auxiliary function(s). Theauxiliary function module 104 may be a module different from theearphone core and may be used for receiving the auxiliary signal(s) andperforming the auxiliary function(s). In the present disclosure, theconversion of the audio signal into the sound signal may be consideredas a main function of the speaker 100, and other functions differentfrom the main function may be considered as the auxiliary function(s) ofthe speaker 100. For example, the auxiliary function(s) of the speaker100 may include receiving a user sound and/or an ambient sound through amicrophone, controlling a broadcasting process of the sound signalthrough a key, or the like, and a corresponding auxiliary functionmodule may include a microphone, a key switch, etc., which may be setaccording to actual needs. The auxiliary signal(s) may be electricsignal(s) related to the auxiliary function(s), optical signal(s)related to the auxiliary function(s), acoustic signal(s) related to theauxiliary function(s), vibration signal(s) related to the auxiliaryfunction(s), or the like, or any combination thereof.

The speaker 100 may further include a core housing 108 for accommodatingthe earphone core 102, the auxiliary function module 104, and theflexible circuit board 106. When the speaker 100 is a bone conductionearphone, an inner wall of the core housing 108 may be directly orindirectly connected to the vibration component in the earphone core.When the user wears the bone conduction earphone, an outer wall of thecore housing 108 may be in contact with the user and transmit themechanical vibration of the vibration component to an auditory nervethrough a bone, so that the human body may hear the sound. In someembodiments, the speaker may include the earphone core 102, theauxiliary function module 104, the flexible circuit board 106, and thecore housing 108.

In some embodiments, the flexible circuit board 106 may be a flexibleprinted circuit board (FPC) accommodated in the inner space of the corehousing 108. The flexible circuit board 106 may have high flexibilityand be adapted to the inner space of the core housing 108. Specifically,in some embodiments, the flexible circuit board 106 may include a firstboard and a second board. The flexible circuit board 106 may be bent atthe first board and the second board so as to adapt to a position of theflexible circuit board in the core housing 108, or the like. Moredetails may refer to descriptions in other parts of the presentdisclosure.

In some embodiments, the speaker 100 may transmit the sound through abone conduction approach. An outer surface of the core housing 108 mayhave a contact surface. The contact surface may be an outer surface ofthe speaker 100 in contact with the human body when the user wears thespeaker 100. The speaker 100 may compress the contact surface against apreset area (e.g., a front end of a tragus, a position of a skull, or aback surface of an auricle), thereby effectively transmitting thevibration signal(s) to the auditory nerve of the user through the boneand improving the sound quality of the speaker 100. In some embodiments,the contact surface may be abutted on the back surface of the auricle.The mechanical vibration signal(s) may be transmitted from the earphonecore to the core housing and transmitted to the back of the auriclethrough the contact surface of the core housing. The vibration signal(s)may then be transmitted to the auditory nerve by the bone near the backof the auricle. In this case, the bone near the back of the auricle maybe closer to the auditory nerve, which may have a better conductioneffect and improve the efficiency of transmitting the sound to theauditory nerve by the speaker 100.

In some embodiments, the speaker 100 may further include a fixingmechanism 110. The fixing mechanism 110 may be externally connected tothe core housing 108 and used to support and maintain the position ofthe core housing 108. In some embodiments, a battery assembly and acontrol circuit may be disposed in the fixing mechanism 110. The batteryassembly may provide electric energy to any electronic component in thespeaker 100. The control circuit may control any function component inthe speaker 100. The function component may include, but be not limitedto, the earphone core, the auxiliary function module, or the like. Thecontrol circuit may be connected to the battery and other functionalcomponents through the flexible circuit board or the wire.

In some embodiments, the fixing mechanism 110 may be an eyeglass rim, ahat, a headgear, other headwear accessories, or the like, or anycombination thereof. For example, the fixing mechanism 110 may be aneyeglass rim. A cavity may be formed inside the eyeglass rim. The cavitymay accommodate the battery assembly, the flexible circuit board, andthe control circuit. In this case, the earphone core 102 may be locatedat the end of the eyeglass temple, which may be located near the ear andprovide the sound signal(s) when the user wears the eyeglasses.

FIG. 2 is a schematic diagram illustrating a structure of a flexiblecircuit board located inside a core housing according to someembodiments of the present disclosure.

In some embodiments, the flexible circuit board may be disposed with anumber of pads. Different signal wires (e.g., audio signal wires,auxiliary signal wires) may be electrically connected to different padsthrough different flexible leads to avoid numerous and complicatedinternal wires issues, which may occur when both audio signal wires andauxiliary signal wires need to be connected to the earphone core or theauxiliary function module. FIG. 3 is an exploded diagram illustrating apartial structure of a speaker according to some embodiments of thepresent disclosure. As shown in FIGS. 2 and 3 , a flexible circuit board44 may at least include a number of first pads 45 and a number of secondpads (not shown in the figures). In some embodiments, the flexiblecircuit board 44 in FIG. 2 may correspond to the flexible circuit board106 in FIG. 1 . At least one of the first pads 45 may be electricallyconnected to auxiliary function module(s). The at least one of the firstpads 45 may be electrically connected to at least one of the second padsthrough a first flexible lead 47 on the flexible circuit board 44. Theat least one of the second pads may be electrically connected to anearphone core (not shown in the figures) through external wire(s) (notshown in the figures). At least another one of the first pads 45 may beelectrically connected to auxiliary signal wire(s). The at least anotherone of first pads 45 and the auxiliary function module(s) may beelectrically connected through a second flexible lead 49 on the flexiblecircuit board 44. In the embodiment, the at least one of the first pads45 may be electrically connected to the auxiliary function module(s).The at least one of the second pads may be electrically connected to theearphone core through the external wire(s). The one of the at least oneof the first pads 45 may be electrically connected to one of the atleast one of the second pads through the first flexible lead 47, so thatthe external audio signal wire(s) and the auxiliary signal wire(s) maybe electrically connected to the earphone core and the auxiliaryfunction modules at the same time through the flexible circuit board,which may simplify a layout of the wiring.

In some embodiments, the audio signal wire(s) may be wire(s)electrically connected to the earphone core and transmitting audiosignal(s) to the earphone core. The auxiliary signal wire(s) may bewire(s) electrically connected to the auxiliary function modules andperforming signal transmission with the auxiliary function modules.

In some embodiments, referring to FIG. 2 , specifically, the flexiblecircuit board 44 may be disposed with the number of pads 45 and two pads(not shown in the figure). The two pads and the number of pads 45 may belocated on the same side of the flexible circuit board 44 and spacedapart. The two pads may be connected to two corresponding pads 45 of thenumber of pads 45 through the flexible lead(s) 47 on the flexiblecircuit board 44. Further, a core housing 41 may also accommodate twoexternal wires. One end of each of the external wires may be welded tothe corresponding pad, and the other end may be connected to theearphone core, so that the earphone core may be connected to the padsthrough the external wires. The auxiliary function modules may bemounted on the flexible circuit board 44 and connected to other pads ofthe number of pads 45 through the flexible lead(s) 49 on the flexiblecircuit board 44.

In some embodiments, wires may be disposed in the fixing mechanism 110of the speaker 100. The wires may at least include the audio signalwire(s) and the auxiliary signal wire(s). In some embodiments, there maybe multiple wires in the fixing mechanism 110. Such wires may include atleast two audio signal wires and at least two auxiliary signal wires.For example, the fixing mechanism 110 may be an eyeglass rim. Theeyeglass rim may be connected to the core housing 41, and the wires maybe wires disposed in the eyeglass rim. One end of each of multiple wiresin the eyeglass rims may be welded to the flexible circuit board 44arranged in the core housing 10, or a control circuit board, and theother end of the wire may enter the core housing 41 and be welded to thepad 45 on the flexible circuit board 44.

As used herein, one end of each of the two audio signal wires of themultiple wires in the eyeglass rims, which may be located in the corehousing 41, may be welded to the two pads 45 by two flexible leads 47,and the other end may be directly or indirectly connected to the controlcircuit board. The two pads 45 may be further connected to the earphonecore through the welding of the flexible lead(s) 49 and the two pad 46and the welding of the two external wires and the pads, therebytransmitting the audio signal(s) to the earphone core.

One end of each of at least two auxiliary signal wires in the corehousing 41 may be welded to the pad 45 by the flexible lead(s) 49, andthe other end may be directly or indirectly connected to the controlcircuit board so as to pass the auxiliary signal(s) received andtransformed by the auxiliary function module(s) to the control circuit(not shown in the figure).

In the approach described above, the flexible circuit board 44 may bedisposed in the core housing 41, and the corresponding pads may befurther disposed on the flexible circuit board 44. Therefore, the wires(not shown in the figure) may enter the core housing 41 and be welded tothe corresponding pads, and further connected to the correspondingauxiliary function module(s) through the flexible leads 47 and theflexible leads 49 on the pads, thereby avoiding a number of wiresdirectly connected to the auxiliary function module(s) to make thewiring in the core housing 41 complicated. Therefore, the arrangement ofthe wirings may be optimized, and the space occupied by the core housing41 may be saved. In addition, when a number of the rim wires aredirectly connected to the auxiliary function module(s), a middle portionof the rim wires may be suspended in the core housing 41 to easily causevibration, thereby resulting in abnormal sounds to affect the soundquality of the earphone core. According to the approach, the wires inthe eyeglass rim may be welded to the flexible circuit board 44 andfurther connected to the corresponding auxiliary function module(s),which may reduce a situation that the wires are suspended from effectingthe quality of the earphone core, thereby improving the sound quality ofthe earphone core to a certain extent.

In some embodiments, the flexible circuit board (also referred to as theflexible circuit board 44) may be further divided. The flexible circuitboard may be divided into at least two regions. One auxiliary functionmodule may be disposed on one of the at least two regions, so that atleast two auxiliary function modules may be disposed on the flexiblecircuit board. Wiring between the audio signal wire(s) and the auxiliarysignal wire(s) and the at least two auxiliary function modules may beimplemented through the flexible circuit board. In some embodiments, theflexible circuit board may include at least a main circuit board and afirst branch circuit board. The first branch circuit board may beconnected to the main circuit board and extend away from the maincircuit board along one end of the main circuit board. The auxiliaryfunction module(s) may include at least a first auxiliary functionmodule and a second auxiliary function module. The first auxiliaryfunction module may be disposed on the main circuit board, and thesecond auxiliary function module may be disposed on the first branchcircuit board. The number of first pads may be disposed on the maincircuit board, and the second pads may be disposed on the first branchcircuit board. In some embodiments, the first auxiliary function modulemay be a key switch. The key switch may be disposed on the main circuitboard, and the first pads may be disposed corresponding to the keyswitch. The second auxiliary function module may be a microphone. Themicrophone may be disposed on the first branch circuit board, and thesecond pads corresponding to the microphone may be disposed on the firstbranch circuit board. The first pads corresponding to the key switch onthe main circuit board may be connected to the second pads correspondingto the microphone on the first branch circuit board through the secondflexible lead(s). The key switch may be electrically connected to themicrophone, so that the key switch may control or operate themicrophone.

In some embodiments, the flexible circuit board may further include asecond branch circuit board. The second branch circuit board may beconnected to the main circuit board. The second branch circuit board mayextend away from the main circuit board along the other end of the maincircuit board and be spaced from the first branch circuit board. Theauxiliary function module(s) may further include a third auxiliaryfunction module. The third auxiliary function module may be disposed onthe second branch circuit board. The number of first pads may bedisposed on the main circuit board. At least one of the second pads maybe disposed on the first branch circuit board, and the other second padsmay be disposed on the second branch circuit. In some embodiments, thethird auxiliary function module may be a second microphone. The secondbranch circuit board may extend perpendicular to the main circuit board.The second microphone may be mounted on the end of the second branchcircuit board away from the main circuit board. The number of pads maybe disposed at the end of the main circuit board away from the secondbranch circuit board.

Specifically, as shown in FIG. 2 and FIG. 3 , the second auxiliaryfunction module may be the first microphone 432 a. The third auxiliaryfunction module may be the second microphone 432 b. As used herein, thefirst microphone 432 a and the second microphone 432 b may both be MEMS(micro-electromechanical system) microphone 432, which may have a smallworking current, relatively stable performance, and high voice quality.The two microphones 432 may be disposed at different positions of theflexible circuit board 44 according to actual needs.

As used herein, the flexible circuit board 44 may include a main circuitboard 441 (or referred to the main circuit board), and a branch circuitboard 442 (or referred to the first branch circuit board) and a branchcircuit board 443 (or referred to the second branch circuit board)connected to the main circuit board 441. The branch circuit board 442may extend in the same direction as the main circuit board 441. Thefirst microphone 432 a may be mounted on one end of the branch circuitboard 442 away from the main circuit board 441. The branch circuit board443 may extend perpendicular to the main circuit board 441. The secondmicrophone 432 b may be mounted on one end of the branch circuit board443 away from the main circuit board 441. A number of pads 45 may bedisposed on the end of the main circuit board 441 away from the branchcircuit board 442 and the branch circuit board 443.

In one embodiment, the core housing 41 may include a peripheral sidewall 411 and a bottom end wall 412 connected to one end surface of theperipheral side wall 411, so as to form an accommodation space with anopen end.

In the embodiment, the branch circuit board 442 and/or the branchcircuit board 443 may be appropriately bent to suit a position of asound inlet corresponding to the microphone 432 on the core housing 41.Specifically, the flexible circuit board 44 may be disposed in the corehousing 41 in a manner that the main circuit board 441 is parallel tothe bottom end wall 412. Therefore, the first microphone 432 a maycorrespond to the bottom end wall 412 without bending the main circuitboard 441. Since the second microphone 432 b may be fixed on theperipheral side wall 411 of the core housing 41, it may be necessary tobend the second main circuit board 441. Specifically, the branch circuitboard 443 may be bent at one end away from the main circuit board 441 sothat a board surface of the branch circuit board 443 may beperpendicular to a board surface of the main circuit board 441 and thebranch circuit board 442. Further, the second microphone 432 b may befixed at the peripheral side wall 411 of the core housing 41 in adirection facing away from the main circuit board 441 and the branchcircuit board 442.

In one embodiment, the first pads 45, the second pads, the firstmicrophone 432 a, and the second microphone 432 b may be disposed on thesame side of the flexible circuit board 44. The second pads may bedisposed adjacent to the second microphone 432 b.

As used herein, the second pads may be specifically disposed at one endof the branch circuit board 443 away from the main circuit board 441 andhave the same direction as the second microphone 432 b and disposed atintervals. Therefore, the second pads may be perpendicular to thedirection of the first pads 45 as the branch circuit board 443 is bent.It should be noted that the branch circuit board 443 may not beperpendicular to the board surface of the main circuit board 441 afterbeing bent, which may be determined according to the arrangement betweenthe side wall 411 and the bottom end wall 412.

Further, another side of the flexible circuit board 44 may be disposedwith a rigid support plate 4 a and a microphone rigid support plate 4 bfor supporting the first pads 45.

As used herein, the rigid support plate 4 a, the rigid support plate 4 b1, and the rigid support plate 4 b 2 may be mainly used to support thecorresponding pads and the microphone 432, and thus may need to havecertain strengths. The materials of the three may be the same ordifferent. The specific material may be polyimide (PI), or othermaterials that may provide the strengths, such as polycarbonate,polyvinyl chloride, etc. In addition, the thicknesses of the three rigidsupport plates may be set according to the strengths of the rigidsupport plates, and actual strengths required by the first pads 45, thesecond pads, the first microphone 432 a, and the second microphone 432b, and be not specifically limited herein.

As used herein, the rigid support plate 4 a, the rigid support plate 4 b1, and the rigid support plate 4 b 2 may be three different regions ofan entire rigid support plate, or three independent bodies spaced apartfrom each other, and be not specifically limited herein.

In one embodiment, the first microphone 432 a and the second microphone432 b may correspond to two microphone components 4 c, respectively (notshown in the figure). In one embodiment, the structures of the twomicrophone components may be the same. A sound inlet 413 may be disposedon the core housing 41. Further, the loud speaking device may be furtherdisposed with an annular blocking wall 414 integrally formed on theinner surface of the core housing 41 at the core housing 41, anddisposed at the periphery of the sound inlet 413, thereby defining anaccommodation space (not shown in the figure) connected to the soundinlet 413.

In one embodiment, the flexible circuit board 44 may be disposed betweena rigid support plate (e.g., the rigid support plate 4 a, the rigidsupport plate 4 b 1, and the rigid support plate 4 b 2) and themicrophone 432. A sound input 444 may be disposed at a positioncorresponding to a sound input 4 b 3 of the microphone rigid supportplate 4 b.

Further, the flexible circuit board 44 may further extend away from themicrophone 432, so as to be connected to other functional components orwires to implement corresponding functions. Correspondingly, themicrophone rigid support plate 4 b may also extend out a distance withthe flexible circuit board in a direction away from the microphone 432.

Correspondingly, the annular blocking wall 414 may be disposed with agap matching the shape of the flexible circuit board to allow theflexible circuit board to extend out of the accommodation space 415. Inaddition, the gap may be further filled with a sealant to furtherimprove the sealing.

The wireprotection cover 172 may be flush with the wire body 171 on the side ofthe wire body 171 facing the bottom of the first mounting groove 111.The side of the wire body 171 facing away from the bottom of the firstmounting groove 111 may still present the shape of the wire body 171,thereby forming the corresponding convex portion 1721.

Further, the top-side edge 131 of the spectacle lens 13 may need to befurther disposed inside the first mounting groove 111. In theembodiment, the top-side edge 131 may be further disposed with theclearance slot 1311 for receiving the convex portion 1721, so that theconnection wire 17 installed inside the first mounting groove 111 may beat least partially accommodated in the clearance slot 1311 correspondingto the top-side edge 131.

Further, the convex portion 1721 may be located in a middle region ofthe wire protection cover 172 along a width direction of the wireprotection cover 172 to form abutting portions 1722 on two sides of theconvex portion 1721. The two abutting portions 1722 may abut on thetop-side edges 131 on two sides of the clearance slot 1311,respectively. As used herein, the width direction of the wire protectioncover 172 may refer to a direction perpendicular to a direction of thewire protection cover 172 along the first mounting groove 111,specifically a direction indicated by W in FIG. 10 .

It may be easy to understand that the depth of the first mounting groove111 may be limited. If the top-side edge 131 of the spectacle lens 13 isflush with the convex portion 1721 of the connection wire 17, or a sideof the wire protection cover 172 and the wire body 171 facing away fromthe bottom of the first mounting groove 111 is flush with the wire body171, an insertion depth of the top-side edge 131 of the spectacle lens13 in the first mounting groove 111 may be reduced, which maydisadvantage the stable installation of the spectacle lens 13 in theeyeglass rim 11. In the embodiment, the top-side edge 131 of thespectacle lens 13 may avoid a portion of the connection wire 17 throughthe clearance slot 1311, so that the top-side edge 131 may furtherextend towards the bottom of the first mounting groove 111 relative tothe clearance slot 1311 and abut on the abutting portions 1722 on thetwo sides of the protruding portion 1721. Therefore, the space occupiedby the connection wire 17 in the first mounting groove 111 may bereduced to a certain extent, so that the spectacle lens 13 may beinstalled deeper inside the first mounting groove 111, thereby improvingthe stability of the spectacle lens 13 in the eyeglass rim 11.

In an application scenario, the eyeglass rim 11 may be thin, and atleast a portion of the convex portion 1721 may be exposed outside thefirst mounting groove 111 to reduce the space of the eyeglass rimoccupied by the connection wire 17, thereby reducing the depth of thefirst mounting groove 111 and improving the stability of the eyeglassrim 11.

As used herein, further referring to FIG. 2 and FIG. 12 , FIG. 12 is apartial structural diagram illustrating part B in FIG. 7 according tosome embodiments of the present disclosure. In one embodiment, the firstbuckle 1321 may include a first sub-edge 13211, a second sub-edge 13212,and a third sub-edge 13213.

As used herein, the first sub-edge 13211 may be disposed adjacent to thetop-side edge 131. The second sub-edge 13212 may be disposed away fromthe top-side edge 131 and opposite to the first sub-edge 13211. Thethird sub-edge 13213 may be connected to the first sub-edge 13211 andthe second sub-edge 13212 on a side of the first sub-edge 13211 and thesecond sub-edge 13212 away from the spectacle lens 13.

In the embodiment, the wire protection cover 172 may further extend tothe first buckle groove 112 along the first sub-edge 13211.

In the way, the wire protection cover 172 may be held in the firstmounting groove 111 and extend to the first buckle groove 112 to behidden in the eyeglass rim 11. Therefore, when a user disassembles thespectacle lens 13 during use, the wire protection cover 172 may not beexposed after the spectacle lens 13 is disassembled to maintain thebeauty of the eyeglasses.

Further, when extending towards the first buckle groove 112, the wireprotection cover 172 may end at a connection between the first sub-edge13211 and the third sub-edge 13213. Certainly, the wire protection cover172 may also not end and continue to extend along the wire body 171, aslong as the wire protection cover 172 is not exposed when the spectaclelens 13 is disassembled.

Referring to FIG. 13 together, FIG. 13 is an enlarged sectional viewillustrating a partial structure of eyeglasses according to anembodiment of the present disclosure. In the embodiment, the eyeglassesmay further include rotating shaft(s) 19.

As used herein, the count of the rotating shaft(s) 19 may be two, and berespectively used to connect the eyeglass rim 11 and the two eyeglasstemples 15 so that the eyeglass rim 11 and the eyeglass temples 15 mayrotate relative to the rotating shaft 19. As used herein, the rotatingshaft 19 may be disposed with a rotating shaft wiring channel 191 in anaxial direction. The connection wire 17 may be disposed inside the shaftwiring channel 191 and extend to the eyeglass rim 11 and the eyeglasstemples 15, respectively.

Specifically, in the embodiment, after the connection wire 17 passesthrough the rotating shaft wiring channel 191, one end of the connectionwire 17 may extend directly to one of the eyeglass temples 15, and theother end of the connection wire 17 may enter the eyeglass rim 11 andfurther extend to another one of the eyeglass temples 15 along the firstmounting groove 111, thereby electrically connecting the two functioncomponents 16 located inside the two eyeglass temples 15, respectively.

In the embodiment, the connection wire 17 near the rotating shaft wiringchannel may not include the wire protection cover 172. The rotatingshaft wiring channel 191 may pass through the rotating shaft 19.

It may be easy to understand that relative positions of structures nearthe rotating shaft 19 may change when the eyeglass rim 11 and theeyeglass temple 15 are folded. At this time, if the connection wire 17located at the connection between the eyeglass rim 11 and the eyeglasstemple 15 is directly disposed around the periphery of the rotatingshaft 19, the connection wire 17 herein may be compressed or pulled,even deformed or broken with the folding of eyeglass rim 11 or eyeglasstemples 15, which may affect the stability of the connection wire 17 andshorten the service life of the connection wire 17.

In the embodiment, the rotating shaft 19 may be disposed with the shaftwiring channel 191 along the axial direction. The connection wire 17located at the connection between the eyeglass rim 11 and the eyeglasstemple 15 may pass through the shaft wiring channel 191. Therefore, whenthe eyeglass rim 11 and the eyeglass temple 15 are folded, theconnection wire 17 located inside the rotating shaft wiring channel 191may only generate a certain amount of rotation with the rotation of therotating shaft 19 to reduce the folding, compressing or pulling of theconnection wire 17, thereby protecting the connection wire 17 to acertain extent, improving the stability of the connection wire 17, andextending the service life of the connection wire 17.

As used herein, in the embodiment, an inner diameter of the rotationshaft wiring channel 191 may be larger than an outer diameter of theconnection wire 17. For example, the inner diameter of the shaft wiringchannel 191 may be twice the outer diameter of the connection wire 17.Accordingly, a binding effect of the inner side wall of the axis wiringchannel 191 on the connection wire 17 may be reduced, thereby reducingthe rotation of the connection wire 17 when the eyeglass rim 11 and theeyeglass temple 15 are folded.

Referring to FIG. 13 and FIG. 14 together, FIG. 14 is a schematicstructural diagram illustrating a rotating shaft and a connection wireof eyeglasses according to an embodiment of the present disclosure. Inthe embodiment, the rotating shaft 19 may include a first rotating shaft192. Two ends of the first rotating shaft 192 may be respectivelyconnected to the eyeglass rim 11 and the eyeglass temple 15. Therotating shaft wiring channel 191 may be disposed along an axialdirection of the first rotating shaft 192. The shaft wiring channel 191may communicate with the outside through a wiring port 1921 disposed onat least one end surface of the first rotating shaft 192. The connectionwire 17 may extend to the eyeglass rim 11 or the eyeglass temples 15through the wiring port 1921.

It should be noted that, in the embodiment, the first rotating shaft 192may be rotatably connected to one of the eyeglass rim 11 and theeyeglass temples 15, and fixedly connected to another, so that theeyeglass rim 11 and the eyeglass temples 15 may be rotatably connectedaround the first rotating shaft 192.

Specifically, in the embodiment, the rotating shaft wiring channel 191may be disposed inside the first rotating shaft 192, and furthercommunicate with the outside through the wiring port 1921.

Specifically, the rotating shaft wiring channel 191 may penetrate atleast one end surface of the first rotating shaft 192 to form the wiringport 1921 of the rotating shaft wiring channel 191. Therefore, theconnection wire 17 may extend from the shaft wiring channel 191 throughthe at least one end surface of the first rotating shaft 192, and thenextend to the eyeglass rim 11 or the eyeglass temples 15. It may be easyto understand that the periphery of the end surface of the firstrotating shaft 192 may have a relatively large movement space. Theconnection wire 17 extending from the end surface of the first rotatingshaft 192 may be accommodated inside the movement space. And if thefirst rotating shaft 192 at the end face is rotatably connected to thecorresponding eyeglass rim 11 or eyeglass temple 15, when the eyeglassrim 11 and the eyeglass temple 15 fold and rotate, the movement spacemay be appropriately buffered a twist of the connection wire 17 near thewiring port 1921 on the end surface with the rotation of the firstrotating shaft 192, thereby further reducing the twisting degree of theconnection wire 17 and improving the stability of connection wire 17.

Referring to FIG. 15 , FIG. 15 is a schematic structural diagramillustrating a first rotating shaft of eyeglasses according to anembodiment of the present disclosure. In the embodiment, the wiring port1921 may include a first wiring port 19211 and a second wiring port19212 respectively disposed on two ends of the first rotating shaft 192.The rotating shaft wiring channel 191 may communicate with the outsidethrough the two wiring ports 1921, so that the connection wire 17 maypass through the two ends of the first rotating shaft 192 and extend tothe eyeglass rim 11 and the eyeglass temple 15 through the first wiringport 19211 and the second wiring port 19212, respectively.

In other words, in the application scenario, the connection wire 17 atthe connection between the eyeglass rim 11 and the eyeglass temple 15may be disposed inside the rotating shaft wiring channel 191 in thefirst rotating shaft 192, and extend from the rotating shaft wiringchannel 191 through the two ends of the first rotating shaft 192,respectively. At this time, since large movement spaces exist on theperiphery of two end surfaces of the first rotating shaft 192, theconnection wire 17 extending from the two end surfaces of the firstrotating shaft 192 may only move or twist slightly without compressingor deforming when the relative rotation occurs between the eyeglass rim11 and the eyeglass temple 15.

Referring to FIG. 14 , in the embodiment, the wiring port 1921 mayinclude a first wiring port 19213 and a second wiring port 19214. Asused herein, the first wiring port 19213 may be disposed on an endsurface of the first rotating shaft 192, and the second wiring port19214 may be disposed on a side wall of the first rotating shaft 192.Therefore, one end of the shaft wiring channel 191 may penetrate the endsurface of the first rotating shaft 192 in the axial direction throughthe first wiring port 19213, and the other end may penetrate the sidewall of the first rotating shaft 192 through the second wiring port19214, and then communicate with the outside. The connection wire 17 mayextend to the eyeglass rim 11 and the eyeglass temple 15 through thefirst wiring port 19213 and the second wiring port 19214, respectively.

Similarly, a large movement space may be disposed near the end face ofthe first rotating shaft 192 of the first wiring port 19213. When arelative movement occurs between the eyeglass rim 11 and the eyeglasstemple 15, the connection wire 17 near the first wiring port 19213 mayonly undergo a relative shift, or a small twist.

In an application scenario, the first rotating shaft 192 may be fixedlyconnected to one of the eyeglass rim 11 and the eyeglass temple 15disposed near the second wiring port 19214, and rotatably connected toanother of the eyeglass rim 11 and the eyeglass temple 15 disposed nearthe first wiring port 19213. That is, the first rotating shaft 192 maybe rotatably connected to one of the eyeglass rim 11 or the eyeglasstemple 15 at the wiring port 1921 disposed on the end surface. The firstrotating shaft 192 may be fixedly connected to another of the eyeglassrim 11 or the eyeglass temple 15 at the wiring port 1921 disposed on theside wall.

In an application scenario, the first rotating shaft 192 may be closedto the eyeglass rim 11 at the first wiring port 19213, and rotatablyconnected to the eyeglass rim 11. The first rotating shaft 192 may beclosed to the eyeglass temple 15 at the second wiring port 19214, andfixedly connected to the eyeglass temple 15.

It should be noted that, in this application scenario, the firstrotating shaft 192 is rotatably connected to the eyeglass rim 11, andthe relative rotation between the eyeglass rim 11 and the eyeglasstemple 15 may cause the relative movement of the connection wire 17 atthe first wiring 19213. However, since the first wiring port 19213 isdisposed on the end surface of the first rotating shaft 192, similar tothe embodiment described above, the end surface of the first rotatingshaft 192 may have a large movement space. When the eyeglass rim 11 andthe eyeglass temple 15 are folded and rotated, and the connection wire17 near the wiring port 1921 on the end surface is twisted to a certainextent with the rotation of the first rotating shaft 192, the movementspace may be appropriately buffered, and the twist may be turned into ashift or a small twist, without compressing or pulling the connectionwire, thereby improving the stability of the connection wire andextending the service life of the connection wire.

In addition, the first rotating shaft 192 may be fixedly connected tothe eyeglass temple 15 at the second wiring port 19214. It may be easyto understand that the eyeglass temple 11 and the first rotating shaft192 may be synchronized when the relative rotation occurs between theeyeglass rim 11 and the eyeglass temple 15. Hence, the connection wire17 in the shaft wiring channel 191 may extend through the second wiringport 19214 into the connection wire 17 of the eyeglass temple 11 withouttwisting, compressing, or pulling. Therefore, at this time, the secondwiring port 19214 may be disposed on the end surface of the firstrotating shaft 192 or on the side wall of the first rotating shaft 192.The relative rotation between eyeglass rim 11 and eyeglass temple 15 maynot cause the twisting, compressing, pulling, etc., of the connectionwire 17 herein.

In other embodiments, if the first rotating shaft 192 and the eyeglasstemple 15 are rotatably connected at the second wiring port 19214, therelative rotation between thereof may allow the connection wire 17 tomove, which may be constrained by the side wall of the first rotatingshaft at the second wiring port 19214, so that the connection wire 17may be compressed between the side wall of the first rotating shaft andthe eyeglass temple 15.

If the first rotating shaft 192 is near the eyeglass temple 15 at thefirst wiring port 19213 and rotatably connected to the eyeglass temple15, the first rotating shaft 192 may be near the eyeglass rim 11 at thesecond wiring port 19214 and fixedly connected to the eyeglass rim 11.For the same reason, when the eyeglass rim 11 and the eyeglass temple 15are folded, the connection wire 17 inside the rotating shaft wiringchannel 191 and near the first wiring port 19213 and the second wiringport 19214 may be still only slightly twisted or moved.

Referring to FIG. 14 , in one embodiment, the rotating shaft 19 mayfurther include a second shaft 193 coaxial with and spaced from thefirst rotating shaft 192.

In the embodiment, the second rotating shaft 193 may be disposed on aside of the first rotating shaft 192 near the first wiring port 19213.Certainly, in other embodiments, the second rotating shaft 193 may alsobe disposed on a side of the first rotating shaft 192 closed to thesecond wiring port 19214.

Referring to FIG. 16 , FIG. 16 is a partial exploded view illustratingeyeglasses according to an embodiment of the present disclosure. In theembodiment, the eyeglass rim 11 may include first lug(s) 113.Specifically, the count of the first lug(s) 113 may be two, and berespectively disposed at two ends of the eyeglass rim 11 connecting tothe two eyeglass temples 15 and protrude towards the correspondingeyeglass temples 15.

The eyeglass temple 15 may include a second lug 1501 and a third lug1502 disposed at intervals. As used herein, the second lug 1501 and thethird lug 1502 may face ends of the eyeglass rim 11 connected to theeyeglass temple 15 at which the lugs are located. In addition, when theuser wears the eyeglasses, the second lug 1501 and the third lug 1502may be connected to a side away from the head of the user, therebymaking the eyeglasses more overall and more beautiful in appearance. Inan application scenario, the second lug 1501 and the third lug 1502disposed at intervals may be formed by disposing a groove in the middleof an end of the eyeglass temple 15 facing the eyeglass rim 11.

Further, ends of the first rotating shaft 192 and the second rotatingshaft 193 closed to each other may be connected to the first lug 113.Ends of the first rotating shaft 192 and the second rotating shaft 193away from each other may be connected to the second lug 1501 and thethird lug 1502, respectively, so as to maintain the first lug 113between the second lug 1501 and the third lug 1502.

As used herein, referring to FIG. 14 continuously, in one embodiment,the first wiring port 19213 may be disposed on an end surface of thefirst rotating shaft 192 near the second rotating shaft 193. The secondwiring port 19214 may be disposed on a side wall of the first rotatingshaft near the second lug 1501. The first rotating shaft may berotatably connected to the first lug 113 and fixedly connected to thesecond lug 1501.

Specifically, in the embodiment, one end of the connection wire 17inside the rotating shaft wiring channel 191 may extend from the firstwiring port 19213 and pass through an interval between the firstrotating shaft 192 and the second rotating shaft 193. Further, in anapplication scenario, the first lug 113 may be disposed with a wiringchannel connected to the first wiring port 19213, so that the connectionwire 17 may further enter the eyeglass rim 11 from the first lug 113.

In addition, the other end of the connection wire 17 inside the rotatingshaft wiring channel 191 may extend from the second wiring port 19214.Further, in an application scenario, the third lug 1502 may be disposedwith a wiring channel communicating with the second wiring port 19214,so that the connection wire 17 may further enter the eyeglass temple 15through the wiring channel of the third lug 1502.

As used herein, the second wiring port 19214 may be a through-holedisposed on a side wall of the first rotating shaft 192, andcommunicated with the rotating shaft wiring channel 191 withoutpenetrating an end of the first rotating shaft 192. In the embodiment,the second wiring port 19214 may be further penetrated along the sidewall of the first rotating shaft 192 to an end of the first rotatingshaft 192 away from the first wiring port 19213. It may be easy tounderstand that, in the embodiment, the second wiring port 19214 mayhave a larger space. Therefore, when the connection wire 17 is moved forsome reason, the restriction on the connection wire 17 may be furtherreduced, and the damage to the side wall of the first rotating shaft 192may be further reduced.

Referring to FIG. 16 , FIG. 17 , and FIG. 18 together, FIG. 17 is aschematic structural diagram illustrating an eyeglass rim and aspectacle lens of eyeglasses according to an embodiment of the presentdisclosure, and FIG. 18 is a partial structural schematic diagramillustrating an eyeglass temple of eyeglasses according to an embodimentof the present disclosures. In the embodiment, the first lug 113 and thesecond lug 1501 may be coaxially disposed with a first accommodatinghole 1131 and a second accommodating hole 15011, respectively. Sizes ofthe first accommodating hole 1131 and the second accommodating hole15011 may be set to allow the first rotating shaft 192 to be insertedinto the first accommodating hole 1131 from the outside of the eyeglasstemple 15 through the second accommodating hole 15011, such that thefirst rotating shaft 192 may be in an interference fit with the secondaccommodating hole 15011 and in a clearance fit with the firstaccommodating hole 1131.

Specifically, the second accommodating hole 15011 may be a through-holepenetrating the second lug 1501. The first accommodating hole 1131 maycorrespond to the second accommodating hole 15011 and penetrate at leasta portion of the first lug 113. As used herein, an inner diameter of thefirst accommodating hole 1131 may be larger than the secondaccommodating hole 15011. An outer diameter of the first rotating shaft192 may be between the first accommodating hole 1131 and the secondaccommodating hole 15011. Therefore, the first rotating shaft 192 may befixedly connected to the eyeglass temple 15 and rotatably connected tothe eyeglass rim 11 so that the eyeglass rim 11 and the eyeglass temple15 may be rotated around the first rotating shaft 192 to be folded orunfolded.

Further, in an embodiment, the first lug 113 and the third lug 1502 maybe coaxially disposed with a third accommodating hole 1132 and a fourthaccommodating hole 15021, respectively. Sizes of the third accommodatinghole 1132 and the fourth accommodating hole 15021 may be set to allowthe second rotating shaft 193 to be inserted into the thirdaccommodating hole 1132 from the outside of the eyeglass temple 15 viathe fourth accommodating hole 15021, such that the second rotating shaft193 may be in an interference fit with the third accommodating hole 1132and in a clearance fit with the fourth accommodating hole 15021, or thesecond rotating shaft 193 may be in a clearance fit with the thirdaccommodating hole 1132 and in an interference fit with the fourthaccommodating hole 15021.

In the embodiment, the third accommodating hole 1132 and the fourthaccommodating hole 15021 may be coaxial with both the firstaccommodating hole 1131 and the second accommodating hole 15011. As usedherein, the third accommodating hole 1132 may penetrate at least aportion of the first lug 113. In one application scenario, the firstaccommodating hole 1131 and the third accommodating hole 1132 may becoaxially penetrated. Specifically, as described in the aboveembodiment, the first lug 113 of the eyeglass rim 11 may be disposedwith a wiring channel connected to the first wiring port 19213. Thefirst accommodating hole 1131 and the third accommodating hole 1132 maybe respectively disposed on both sides of the wiring channel locatedinside the first lug 113 and both pass through the wiring channel. Thefourth accommodating hole 15021 may penetrate the third lug 1502. Asused herein, the outer diameter of the second rotating shaft 193 may bebetween the inner diameter of the third accommodating hole 1132 and theinner diameter of the fourth accommodating hole 15021. The innerdiameter of the third accommodating hole 1132 may be larger than thefourth accommodating hole 15021. Alternatively, the inner diameter ofthe fourth accommodating hole 15021 may be larger than the thirdaccommodating hole 1132. Therefore, the second rotating shaft 193 may befixedly connected to the eyeglass temple 15 and rotatably connected tothe eyeglass rim 11, or the second rotating shaft 193 may be fixedlyconnected to the eyeglass rim 11 and rotatably connected to the eyeglasstemple 15, so that the eyeglass rim 11 and the eyeglass temple 15 may berotated around the first rotating shaft 192 to be folded or unfolded.

In one embodiment, the second rotating shaft 193 may be a solid shaft,and the diameter may be less than that of the first rotating shaft 192.In the wearing state, the second shaft 193 may be located on the upperside of eyeglass temple 15, and the first rotating shaft may be locatedon the lower side of eyeglass temple 15.

It should be noted that, since the rotating shaft wiring channel 191 maybe disposed inside the first rotating shaft 192, the outer diameter ofthe first rotating shaft 192 may be larger, which may adversely satisfyaesthetic needs of the user. Therefore, in the embodiment, the secondrotating shaft 193 having a smaller outer diameter may be furtherdisposed. Hence, when the user wears the eyeglasses, the second rotatingshaft 193 may be disposed on an upper portion that is easily found, andthe first rotating shaft 192 may be disposed on a lower portion that isnot easily observed. Since the outer diameter of the second rotatingshaft 193 is smaller, the overall aesthetic effect of the eyeglasses maybe improved to a certain extent.

Certainly, in other embodiments, the first rotating shaft 192 and thesecond rotating shaft 193 may also be other cases. For example, thesecond rotating shaft 193 may also be a hollow shaft, and the diameterof the second rotating shaft 193 may be larger than the diameter of thefirst rotating shaft 192. Alternatively, in the wearing state, thesecond rotating shaft 193 may be disposed on a lower side of theeyeglass temple 15, and the first rotating shaft 192 may be disposed onan upper side of the eyeglass temple 15, or the like, and be not limitedherein.

In addition, referring to FIG. 14 , a connection between an end surface1922 of the first rotating shaft 192 for disposing the first wiring port19213 and an inner wall surface 1923 of the first rotating shaft 192 fordefining the rotating shaft wiring channel 191 may be arc-shaped. It maybe easy to understand that, when the rotation between the eyeglass rim11 and the eyeglass temple 15 through the rotating shaft 19 occurs,since the first rotating shaft 192 and the eyeglass rim 11 are rotatablyconnected, the connection wire 17 at the first wiring port 19213 may bemoved. In the embodiment, the connection between the end surface 1922 ofthe first rotating shaft 192 and the inner wall surface 1923 may bearc-shaped. Therefore, when the connection wire 17 at the first wiringport 19213 moves and contacts with the first rotating shaft 192, theconnection wire 17 may be avoided to be cut if the connection is toosharp, thereby further protecting the connection wire 17.

In an application scenario, a connection between the end surface of thefirst rotating shaft 192 for disposing the second wiring port 19214 andthe inner wall surface 1923 of the first rotating shaft 192 for definingthe rotating shaft wiring channel 191 may also be arc-shaped. Similarly,in this way, the connection wire 17 may be further protected.

It should be noted that the above description of the rotating shaft andwiring in the eyeglasses may be only specific examples, and should benot considered as the only feasible implementation. Obviously, for thoseskilled in the art, after understanding the basic principle of therotating shaft and wiring in the eyeglasses, it may be possible to makevarious modifications and changes in the form and details of thespecific manner and operation of implementing the rotating shaft andwiring in the eyeglasses without departing from these principles, butthese modifications and changes are still within the scope describedabove. For example, the branch circuit board may also include a thirdpad and a third flexible circuit board. All such variations may bewithin the protection scope of the present disclosure.

In some embodiments, as shown in FIG. 1 , a speaker includes an earphonecore 102 and a core housing 108. In an application scenario, the speakerof the eyeglasses may include, but is not limited to, a bone conductionspeaker, an air conduction speaker. The following may further illustratea fitting position on human body based on the bone conduction speaker.It should be known that without departing from the principles, thefollowing illustrations may also be applied to the air conductionspeaker.

In some embodiments, the position of the speaker relative to theeyeglass temple 15 may not be fixed. Specifically, the core housing 108may be rotated to change the position of each speaker relative to theconnected eyeglass temple 15, thus the speaker may fit on differentparts of the user's body, and the user may adjust it based on his or herpreferences. Due to the vibrations transmitted by different bones aredifferent, users may feel different sound qualities, and it is alsoconvenient for users with different sizes of head. For example, in FIG.7 , the speaker may be fixed on the ear by the eyeglass temple 15, andthe speaker may be located behind the ear. In some embodiments, theconnecting end of the eyeglass temple 15 and the speaker may be setaccording to a position that the user is accustomed to. For example, thespeaker and the eyeglass temple 15 may be connected by hingedconnection, if the user is used to placing the speaker behind the ear,the speaker may be set behind the ear by adjusting a hinge component. Itshould be noted that, the connection between the eyeglass temple 15 andthe speaker 21 is not limited to the connection described above. Forexample, the eyeglass temple 15 and the speaker may also be connected byclamping. In some embodiments, the speaker may be fitted to any parts ofthe user's head, such as the top of the head, the forehead, cheeks,sideburns, auricles, the back of auricles, or the like. For example, abracket spanning the top of the head may be arranged between theeyeglass temples 15 to reduce the supporting force of the nose bridge onthe eyeglasses, and the speaker may be arranged on the bracket. In someembodiments, the way the bone conductive earphone fitted to the head maybe surface fitted or point fitted. The contact surface may be arrangedwith a gradient structure, and the gradient structure refers to an areawhere the height of the contact surface changes. The gradient structuremay include a convex/concave structure, a step-like structure, etc., onthe outside of the contact surface (the side that is fitted to theuser), or on the inside of the contact surface (the side facing awayfrom the user).

It should be noted that the above illustration of the fitting positionof the speaker is only a specific example and should not be regarded asthe only feasible implementation solution. Obviously, for those skilledin the art, after understanding the basic principles of fitting, it ispossible to make various modifications and changes in forms and detailsto the specific methods and steps of fitting without departing from theprinciples, but the modifications and changes are still within the scopeillustrated above. For example, the position of clamping may be adjustedbased on the fitting part of the speaker and the head. Such deformationsare all within the protection scope of the present disclosure.

FIG. 19 is a structural diagram and an application scenario of a boneconduction speaker according to some embodiments of the presentdisclosure. Referring to FIG. 1 and FIG. 19 , the structural diagram inFIG. 19 illustrating a speaker including the earphone core 102 and thecore housing 108 in FIG. 1 . The following only takes the boneconduction speaker as an example to illustrate the application scenarioand structure of the speaker. In some embodiments, as shown in FIG. 19 ,the bone conduction speaker may include a driving component 1901, atransmission component 1902, a panel 1903 (the panel 1903 may also bereferred to as a housing panel, which is a panel on the core housingfacing human), a housing 1904, or the like. Referring to FIG. 1 , thepanel 1903 and the housing 1904 are consistent with the core housing(shown in FIG. 1 ). The driving component 1901 and the transmissioncomponent 1902 are consistent with the earphone core 102 (shown in FIG.2 ). In some embodiments, the housing 1904 may include a housing backpanel and housing side panels. The housing back panel is connected withthe panel 1903 through the housing side panels. The driving component1901 may transmit vibration signal(s) to the panel 1903 and/or thehousing 1904 through the transmission component 1902, so as to transmita sound to human body by contacting human skin through the panel 1903 orthe housing 1904. In some embodiments, the panel 1903 and/or the housing1904 may be in contact with human skin at the tragus, so as to transmita sound to human body. In some embodiments, the panel 1903 and/or thehousing 1904 may be in contact with human skin on the back of theauricle.

In some embodiments, a straight line B (or a vibrating direction of adriving device) of a driving force generated by the driving component1901 and a normal line A of the panel 1903 may form an angle θ. In otherwords, the straight line B is not parallel to the normal line A.

The panel has an area that contacts or abuts the user's body, such ashuman skin. It should be understood that when the panel is covered withother materials (such as silicone and other soft materials) to enhancethe user's wearing comfortability, the panel and the user's body are notin direct contact, but abut against each other. In some embodiments,when the bone conduction speaker is worn on the user's body, the wholearea of the panel contacts or abuts the user's body. In someembodiments, when the bone conduction speaker is worn on the user'sbody, a part of the panel contacts or abuts the user's body. In someembodiments, the area of the panel contacting or abutting the user'sbody may account for more than 50% of the entire area of the panel. Morepreferably, it may account for more than 60% of the entire area of thepanel. In general, the area of the panel contacting or abutting theuser's body may be flat or curved.

In some embodiments, when the area of the panel contacting or abuttingthe user's body is a flat surface, its normal line meets the generaldefinition, that is, a dashed line perpendicular to the flat surface. Insome embodiments, when the area contacting or abutting the user's bodyof the panel is a curved surface, its normal line is the average normalline of the area, wherein, the average normal line is defined asfollows:

$\begin{matrix}{= \frac{∯_{S}{\hat{r}{ds}}}{❘{∯_{S}{\hat{r}{ds}}}❘}} & (1)\end{matrix}$

where, {circumflex over (r)}₀ is the average normal line; {circumflexover (r)} is the normal line of any point on the curved surface; ds is asurface unit.

Further, the curved surface is a quasi-flat surface that is close to theflat surface. That is, the curved surface is a surface that an anglebetween a normal line of any point of at least 50% of the area on thecurved surface and the average normal line is less than a set threshold.In some embodiments, the set threshold may be less than 10°. In someembodiments, the set threshold may be less than 5°.

In some embodiments, the straight line B of the driving force and thenormal line A′ of the area of the panel 1903 for contacting or abuttingthe user's body may form the angle θ. A value range of the angle θ maybe 0<θ<180°. Further, the value range may be 0<θ<180° and not equal to90°. In some embodiments, it is assumed that the straight line B has apositive direction pointing to the outside of the bone conductionspeaker, and the normal line A of the panel 1903 (or the normal line A′of a contact surface of the panel 1903 and the human skin) also has apositive direction pointing to the outside of the bone conductionspeaker. Thus, the angle θ formed by the normal line A or A′ and thestraight line B in the positive direction is an acute angle, that is,0<θ<90°. More descriptions about the normal line A and A′ may be foundin FIG. 21 and the descriptions thereof.

FIG. 20 is a schematic diagram illustrating a direction of an includedangle according to some embodiments of the present disclosure. As shownin FIG. 20 , in some embodiments, a driving force generated by a drivingdevice has a component in a first quadrant and/or a third quadrant of anXOY plane coordinate system. As used herein, the XOY plane coordinatesystem is a reference coordinate system whose origin O is located on acontact surface between the panel and/or the housing and the human bodyafter the bone conduction speaker is worn on the human body. The X axisis parallel to the coronal axis of the human body, the Y axis isparallel to the sagittal axis of the human body, and the positivedirection of the X axis faces the outside of the human body, thepositive direction of the Y axis faces the front of the human body.Quadrants should be understood as four regions divided by the horizontalaxis (such as X axis) and the vertical axis (such as Y axis) in arectangular coordinate system. Each region is a quadrant. The quadrantis centered at the origin, and the X axis and Y axis are the dividinglines. The upper right region (the region enclosed by the positive halfaxis of the X axis and the positive half axis of the Y axis) is thefirst quadrant, the upper left region (the region enclosed by thenegative half axis of the X axis and the positive half axis of the Yaxis) is the second quadrant, the lower left region (the region enclosedby the positive half axis of the X axis and the negative half axis ofthe Y axis) is the third quadrant, and the lower right region (theregion enclosed by the positive half axis of the X axis and the negativehalf axis of the Y axis) is the fourth quadrant. The points on the Xaxis and the Y axis do not belong to any quadrant. It should beunderstood that the driving force in the embodiment may be directlylocated in the first quadrant and/or the third quadrant of the XOY planecoordinate system, or the driving force may point to other directions,but the projection or component in the first quadrant and/or the thirdquadrant is not equal to 0 in the XOY plane coordinate system, and theprojection or component in a direction of a Z axis may be equal to 0 ornot equal to 0. As used herein, the Z axis is perpendicular to the XOYplane and passes through the origin O. In some embodiments, the angle θbetween the straight line of the driving force and the normal line ofthe area contacting or abutting the user's body of the panel may be anyacute angle, for example, the range of the angle θ is 5°α80°. Morepreferably, the range is 15° ˜70°. More preferably, the range is25°˜60°. More preferably, the range is 25° ˜50°. More preferably, therange is 28°˜50°. More preferably, the range is 30° ˜39°. Morepreferably, the range is 31°˜38°. More preferably, the range is 32°˜37°. More preferably, the range is 33°˜36°. More preferably, the rangeis 33° ˜35.8°. More preferably, the range is 33.5°˜35°. Specifically,the angle θ may be 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, 34.2°,35°, 35.8°, 36°, 37°, 38°, etc., wherein the error is controlled within0.2°. It should be noted that the illustrations of the driving forcedirection described above should not be interpreted as a limitation ofthe driving force in the present disclosure. In other embodiments, thedriving force may also have component in the second and fourth quadrantsof the XOY plane coordinate system, even the driving force may belocated on the Y axis, or the like.

FIG. 21 is a structural diagram of a bone conduction speaker acting onhuman skin and bones according to the present disclosure.

In some embodiments, the straight line of the driving force is collinearor parallel to the straight line of the vibration of the driving device.For example, in a driving device based on the moving-coil principle, thedirection of the driving force may be the same as or opposite to thevibrating direction of the coil and/or the magnetic circuit component.The panel may have a flat surface or curved surface, or there are aplurality of protrusions or grooves on the panel. In some embodiments,when the bone conduction speaker is worn on the user's body, the normalline of the area contacting or abutting the user's body of the panel isnot parallel to the straight line of the driving force. In general, thearea contacting or abutting the user's body of the panel is flatrelatively. Specifically, it may have a flat surface, or a quasi-flatplane with little curvature. When the area contacting or abutting theuser's body of the panel has a flat surface, the normal line of anypoint on it may be the normal line of the area. At this time, the normalline A of the panel 1903 may be parallel or coincident to the normalline A′ of the contact surface between the panel 1903 and human skin.When the panel used to contact the user's body is non-planar, the normalline of the area may be the average normal line. More detaileddefinition of the average normal line may be found in FIG. 19 and thedescriptions thereof. In some other embodiments, when the panel used tocontact the user's body is non-planar, the normal line of the area mayalso be determined as follows: selecting a certain point in an area whenthe panel is in contact with human skin, determining a tangent plane ofthe panel at the selected point, determining a straight line that passesthrough the point and is perpendicular to the tangent plane, anddesignating the straight line as the normal line of the panel. When thepanel used to contact the user's body is non-planar, different pointscorrespond to different tangent planes of the panel, and the determinednormal line may also be different. At this time, the normal line A′ isnot parallel to the normal line A of the panel. According to a specificembodiment of the present disclosure, the straight line of the drivingforce (or the straight line of the vibration of the driving device) andthe normal line of the area may form an angle θ, where 0<θ<180°. In someembodiments, when the straight line of the driving force has a positivedirection pointing to the outside of the bone conduction speaker fromthe panel (or the contact surface between the panel and/or the housingand human skin), and the normal line of the designated panel (or thecontact surface between the panel and/or the housing and human skin) hasa positive direction pointing to the outside of the bone conductionspeaker, the angle formed by the two straight lines in the positivedirection is an acute angle.

As shown in FIG. 21 , the bone conduction speaker may include a drivingdevice (also referred to as a transducer in other embodiments), atransmission component 1803, a panel 1801, and a housing 1802. In someembodiments, a coil 1804 and a magnetic circuit component 1807 are bothring-shaped. In some embodiments, the driving device adopts amoving-coil driving mode, and includes the coil 1804 and the magneticcircuit component 1807.

In some embodiments, the coil 1804 and the magnetic circuit component1807 have axes parallel to each other. The axis of the coil 1804 or themagnetic circuit component 1807 is perpendicular to the radial plane ofthe coil 1804 and/or the magnetic circuit component 1807. In someembodiments, the coil 1804 and the magnetic circuit component 1807 havethe same central axis. The central axis of the coil 1804 isperpendicular to the radial plane of the coil 1804 and passes throughthe geometric center of the coil 1804. The central axis of the magneticcircuit component 1807 is perpendicular to the radial plane of themagnetic circuit component 1807 and passes through the geometric centerof the magnetic circuit component 1807. The axis of the coil 1804 or themagnetic circuit component 1807 and the normal line of the panel 1801may form the angle θ described above.

Merely by way of example, the relationship between the driving force Fand the deformation S of the skin will be illustrated below combinedwith FIG. 21 . When the straight line of the driving force generated bythe driving device is parallel to the normal line of the panel 1801(i.e., the angle θ is zero), the relationship between the driving forceand the total deformation of the skin is:

F _(⊥) =S _(⊥) ×E×A/h  (2)

where, F_(⊥) denotes the driving force, S_(⊥) denotes the totaldeformation of the skin in the direction perpendicular to the skin, Edenotes the elastic modulus of the skin, A denotes the contact areabetween the panel and the skin, h denotes a total thickness of the skin(i.e., the distance between the panel and the bone).

When the straight line of the driving force generated by the drivingdevice is parallel to the normal line of the area contacting or abuttingthe user's body of the panel (i.e., the angle θ is 90°), therelationship between the driving force in the vertical direction and thetotal deformation of the skin may be shown in Equation (3):

F _(//) =S _(//) ×G×A/h  (3)

where, F_(//) denotes the driving force, S_(//) denotes the totaldeformation of the skin in the direction parallel to the skin, G denotesthe shear modulus of the skin, A denotes the contact area between thepanel and the skin, h denotes total thickness of the skin (i.e., thedistance between the panel and the bone).

The relationship between the shear modulus G and the elastic modulus Eis:

G=E/2(1+γ)  (4)

where, γ denotes the Poisson's ratio of the skin 0<γ<0.5. Thus the shearmodulus G is less than the elastic modulus E, and under the same drivingforce, the corresponding total deformation of the skin S_(//)>S_(⊥).Generally, the Poisson's ratio of the skin is close to 0.4.

When the straight line of the driving force generated by the drivingdevice is not parallel to the normal line of the area contacting orabutting the user's body of the panel, the driving force in thehorizontal direction and the driving force in the vertical direction areexpressed as the Equation (5) and Equation (6), respectively:

F _(⊥) =F×cos(θ)  (5)

F _(//) =F×sin(θ)  (6)

where, the relationship between the driving force F and the deformationS of the skin may be shown in the following equation:

$\begin{matrix}{S = {\sqrt[2]{S_{\bot}^{2} + S_{//}^{2}} = {\frac{h}{A} \times F \times \sqrt[2]{\left( {{\cos(\theta)}/E} \right)^{2} + \left( {{\sin(\theta)}/G} \right)^{2}}}}} & (7)\end{matrix}$

When the Poisson's ratio is 0.4, the descriptions regarding therelationship between the angle θ and the total deformation of the skinmay be found elsewhere of the present disclosure.

FIG. 22 is a diagram illustrating an angle-relative displacementrelationship of a bone conduction speaker according to some embodimentsof the present disclosure. As shown in FIG. 22 , the relationshipbetween the angle θ and the total deformation of the skin is that thegreater the angle θ, and the greater the relative displacement, thegreater the total deformation S of the skin. The greater the angle θ,and the less the relative displacement, the less the deformation S_(⊥)of the skin in the vertical direction of the skin. When the angle θ isclose to 90°, the deformation S_(⊥) of the skin in the verticaldirection of the skin gradually tends to 0.

The volume of the bone conduction speaker in the low frequency part ispositively correlated with the total deformation of the skin S. Thelarger the S, the larger the volume of the bone conduction speaker inlow frequency. The volume of the bone conduction speaker in the highfrequency part is positively correlated with the deformation S_(⊥) ofthe skin in the vertical direction of the skin. The larger the S_(⊥),the larger the volume of the bone conduction speaker in low frequency.

When the Poisson's ratio of the skin is 0.4, the detailed illustrationof the relationship between the angle θ and total deformation of theskin S, the deformation S_(⊥) of the skin in the vertical direction ofthe skin may be found in FIG. 22 . As shown in FIG. 22 , therelationship between the angle θ and the total deformation of the skin Sis that the larger the angle θ and the larger the total deformation ofthe skin S, the larger the volume of the corresponding bone conductionspeaker in the low frequency part. As shown in FIG. 22 , therelationship between the angle θ and the deformation S_(⊥) of the skinin the vertical direction of the skin is that the larger the angle θ andthe smaller the deformation S_(⊥) of the skin in the vertical directionof the skin, the smaller the volume of the corresponding bone conductionspeaker in the high frequency part.

It may be seen from Equation (7) and curves in the FIG. 22 that with theincrease of the angle θ, the speed at which the total deformation of theskin S increases is different from the speed at which the deformationS_(⊥) of the skin in the vertical direction of the skin decreases. Thespeed at which the total deformation of the skin S increases becomesfaster at first, and then becomes slower, and the speed at which thedeformation S_(⊥) of the skin in the vertical direction of the skindecreases becomes faster and faster. In order to balance the volume ofthe bone conduction speaker in the low frequency part and the highfrequency part, the angle θ should be at an appropriate value, forexample, within a range of θ is 5°˜80°, 15°˜70°, 25°˜50°, 25°˜35°,25°˜30°, or the like.

FIG. 23 is a schematic diagram illustrating frequency response curves ofa bone conduction speaker in a low-frequency part correspond todifferent angles 8 according to some embodiments in the presentdisclosure. As shown in FIG. 23 , the panel is in contact with the skinand transmits vibration to the skin. During this process, the skin mayalso affect the vibration of the bone conduction speaker, so as toaffect the frequency response curve of the bone conduction speaker. Fromthe above analysis, it is found that the larger the included angle, thelarger the total deformation of the skin under the same driving force,and for the bone conduction speaker, it is equivalent to that theelasticity of the skin relative to the panel decreases. It may befurther understood that when a certain angle θ is formed between thestraight line of the driving force generated by the driving device andthe normal line of the area contacting or abutting the user's body ofthe panel. Especially when the angle θ increases, the resonance peak inthe low frequency area of the frequency response curve may be adjustedto a lower frequency area, thus making the low frequency to dive deeperand increasing signals in the low frequencies. Compared with othertechniques to improve the low frequency components of the sound (e.g.,adding a vibration transmission plate to the bone conduction speaker),setting the included angle may suppress the increase of the vibrationeffectively while increasing the energy of the low frequency, so as toreduce the sense of vibration, which improves the sensitivity of the lowfrequency of the bone conduction speaker significantly, and improves thesound quality and human experience. It should be noted that, in someembodiments, the increase of the low frequency and the reduction of thevibration may be expressed as when the angle θ increases in the range of(0,90°), the energy in the range of the low frequency of the vibrationor the sound signal(s) increases, and the sense of vibration alsoincreases, but the degree of energy increase in the low frequency rangeis greater than the degree of vibration sensation increase. Thus, inrelative effect, the vibration sensation is reduced relatively. It maybe seen in FIG. 23 , when the included angle is relatively large, theresonance peak in the low frequency area may appear in a lower frequencyrange, which extends the flat part of the frequency curvature, so as toimprove the sound quality of the speaker.

It should be noted that the illustration of the bone conduction speakerdescribed above is only a specific example, and should not be regardedas the only feasible implementation. Obviously, for those skilled in theart, after the basic principles of the bone conduction speaker, it maybe possible to make various modifications and changes in forms anddetails of the specific methods and steps for implementing the boneconduction speaker without departing from the principles, but themodifications and changes are still within the scope illustrated above.For example, the minimum angle θ between the straight line of thedriving force generated by the driving device and the normal line of thearea contacting or abutting the user's body of the panel may be anyacute angle. The acute angle herein is not limited to 5°˜80° describedabove. The angle θ may be less than 5°, such as 1°, 2°, 3°, 4°, etc. Inother embodiments, the angle θ may be larger than 80° and less than 90°,such as 81°, 82°, 85°, etc. In some embodiments, the specific value ofthe angle θ may not be an integer (e.g., 81.3°, 81.38°). Suchdeformations are all within the protection scope of the presentdisclosure.

In some embodiments, the speaker described above may also transmit thesound to the user through air conduction. When the air condition is usedto transmit the sound, the speaker may include one or more soundsources. The sound source may be located at a specific position of theuser's head, for example, the top of the head, a forehead, a cheek, atemple, an auricle, the back of an auricle, etc., without blocking orcovering an ear canal. FIG. 24 is a schematic diagram illustratingtransmitting a sound through air conduction according to someembodiments of the present disclosure.

As shown in FIG. 24 , a sound source 2810 and a sound source 2820 maygenerate sound waves with opposite phases (“+” and “−” in the figure mayindicate the opposite phases). For brevity, the sound sources mentionedherein may refer to sound outlets of the speaker that may output sounds.For example, the sound source 2810 and the sound source 2820 may be twosound outlets respectively located at specific positions of the speaker(e.g., the core housing 108, or the eyeglass temple 15).

In some embodiments, the sound source 2810 and the sound source 2820 maybe generated by the same vibration device 2801. The vibration device2801 may include a diaphragm (not shown in the figure). When thediaphragm is driven to vibrate by an electric signal, the front side ofthe diaphragm may drive air to vibrate. The sound source 2810 may format the sound output through a sound guiding channel 2812. The back ofthe diaphragm may drive air to vibrate, and the sound source 2820 may beformed at the sound output hole through a sound guiding channel 2822.The sound guiding channel may refer to a sound transmission route fromthe diaphragm to the corresponding outlet. In some embodiments, thesound guiding channel may be a route surrounded by a specific structure(e.g., the core housing 108 in FIG. 1 , or the eyeglass temple 15 inFIG. 7 ) on the speaker. It should to be known that in some alternativeembodiments, the sound source 2810 and the sound source 2820 may also begenerated by different vibrating diaphragms of different vibrationdevices, respectively.

Among the sounds generated by the sound source 2810 and the sound source2820, one portion may be transmitted to the ear of the user to form thesound heard by the user. Another portion may be transmitted to theenvironment to form a leaked sound. Considering that the sound source2810 and the sound source 2820 are relatively close to the ears of theuser, for convenience of description, the sound transmitted to the earsof the user may be referred to as a near-field sound. The leaked soundtransmitted to the environment may be referred to as a far-field sound.In some embodiments, the near-field/far-field sounds of differentfrequencies generated by the speaker may be related to a distancebetween the sound source 2810 and the sound source 2820. Generallyspeaking, the near-field sound generated by the speaker may increase asthe distance between the two sound sources increases, while thegenerated far-field sound (the leaked sound) may increase withincreasing the frequency.

For the sounds of different frequencies, the distance between the soundsource 2810 and the sound source 2820 may be designed, respectively, sothat a low-frequency near-field sound (e.g., a sound with a frequency ofless than 800 Hz) generated by the speaker may be as large as possibleand a high-frequency far-field sound (e.g., a sound with a frequencygreater than 2000 Hz) may be as small as possible. In order to implementthe above purpose, the speaker may include two or more sets of dualsound sources. Each set of the dual sound sources may include two soundsources similar to the sound source 2810 and the sound source 2820, andgenerate sounds with specific frequencies, respectively. Specifically, afirst set of the dual sound sources may be used to generate lowfrequency sounds. A second set of the dual sound sources may be used togenerate high frequency sounds. In order to obtain more low-frequencynear-field sounds, the distance between two sound sources in the firstset of the dual sound sources may be set to a larger value. Since thelow-frequency signal has a longer wavelength, the larger distancebetween the two sound sources may not cause a large phase difference inthe far-field, and not form excessive leaked sound in the far-field. Inorder to make the high-frequency far-field sound smaller, the distancebetween the two sound sources in the second set of the dual soundsources may be set to a smaller value. Since the high-frequency signalhas a shorter wavelength, the smaller distance between the two soundsources may avoid the generation of the large phase difference in thefar-field, and thus the generation of the excessive leaked sounds may beavoided. The distance between the second set of the dual sound sourcesmay be less than the distance between the first set of the dual soundsources.

It should be noted that the above description of the sound conductionmanner for changing the air conduction may be only a specific example,and should not be considered as the only feasible implementation.Obviously, for those skilled in the art, after understanding the basicprinciples of the air conduction, it may be possible to target airconduction speaker of different shapes and structures without departingfrom these principles, but these changes may still be within the scopeof the above description. For example, the sound guiding channel 2822may be disposed in the eyeglasses according to other descriptions. Allsuch variations are within the protection scope of the presentdisclosure.

The beneficial effects of the embodiments of the present disclosure mayinclude but be not limited to the following. (1) Through the rotatingshaft, the eyeglass rim and eyeglass temple may be connected, therebyprotecting the connection wire in the eyeglasses, and extending the lifeof the connection wire. (2) The flexible circuit board may simplify thewiring manner in the speaker. (3) The user may adjust the fittingposition of the speaker according to his or her own preferences andhabits, which meets the requirement of the user. (4) The sound qualityof the speaker may be improved by adjusting the angle θ between thenormal line A of the panel or the normal line A′ of the panel contactinghuman skin and the straight line B of the driving force generated by thedriving device. It should be noted that different embodiments may havedifferent beneficial effects. In different embodiments, the possiblebeneficial effects may be any one or a combination of the above, and maybe any other beneficial effects that may be obtained.
